the PFF stuff is probably the most accessible to begin with for sure
a lot of the stuff in the data bowl is heavily analytical
but for me the most important things to look at schematically would be:
- the general move towards the passing game vs the running game via rules and progression of the game in the sport more generally
- the quickening of throwing times and designed/schemed short/quick throws mitigating the impact of a good edge rusher somewhat
- the importance of coverage in lengthening time to throw
- the ability for good man coverage to allow for the blitz and thus hurrying up throwing times again (leading to shorter routes and therefore lower ADOT which restricts the playing space and allows corners to play closer to the receivers in man and allow them to be more confident triggering underneath in zone albeit we saw the downside to this with the westry TD given up only 2 days ago lol)
in terms of edge guys you can talk about the value of sacks vs pressures and how sacks are valuable but not predictive whereas pressures do correlate - but it means that in most cases on a pass play the ball will go in the air somewhere into coverage because the only way it doesnt is if there's a sack
you can examine the way that edge rushers often get paid for past sack production despite it's non-predictive nature and that there's a market inefficiency there to be exploited - especially as coverage sacks count the same in sack totals as high quality sacks (and count more than a forced interception via a pressure or qb hit)
i wouldnt necessarily talk about more nickel and dime beyond the idea that it just means that you need *more* corners because it also means that you're more likely to get more from college because that game changed quicker than the NFL in that way
but looking at market inefficiencies in contracts/pricing is a great idea for sure
